A UWB Filter Using a Dual-mode Ring Resonator with Spurious Passband Suppression

A novel, compact, microstrip bandpass filter for ultra-wideband (UWB) radio systems is proposed. This filter has a 3 dB fractional bandwidth of 60 percent, with low insertion loss and sharp rejection. Based on a dual-mode ring resonator structure and w...
